Prospective Evaluation of The Prevalence of Gastric Helicobacter Pylori Infection in Patients With Gerd, Barrett's Esophagus, Barrett's Dysplasia, and Barrett's Adenocarcinoma

Abstract

Barrett's high-grade dysplasia and adenocarcinoma are significantly more prevalent in patients who are not infected with H. pylori. H. pylori appears to have a protective effect against the development of Barrett's adenocarcinoma.
